Answer:

3 tablets are needed for a 53-lb child

Explanation:

1 lb = 0.4536 kg

So, 53 lb = (53\times 0.4536)kg=24 kg

So, weight of the child is 24 kg

For 1 kg body, recommended dosage is 10 mg

Hence, for 24 kg body, recommended dosage is (10\times 24)mg or 240 mg

80 mg of acetaminophen is present in 1 tablet

So, 240 mg acetaminophen is present in \frac{1}{80}\times 240 tablets or 3 tablets.

So, 3 tablets are needed for a 53-lb child

53 pounds divided by 2.2 kilograms to get the converted weight which is 24.09 kilograms. Round this off to 24 kgs. 10 mg/kg multiply this to 24 kg, it would be 240 mg. 240 mg divided by 80 is 3. Therefore, a 53−lb child requires to have a dosage of 3 tablets.

<h3>Natural Disaster?</h3>
  • Large-scale geological or meteorological phenomena that have the potential to cause loss of life or property are considered natural disasters.
  • Tornadoes and severe storms are examples of these catastrophes. Tropical Storms and Hurricanes. Floods.
  • They release significant amounts of gas and dust into the atmosphere, particularly the upper atmosphere, which temporarily alters the climate on Earth.
  • Large volcanic eruptions should be followed by a drop in the average surface temperature, which is actually seen and lasts for typically 1 to 3 years.
  • Deforestation and the combustion of fossil fuels have detrimental environmental effects that directly affect the biosphere. Pollutant emissions and carbon dioxide have a negative impact on all types of life.

Calculate the enthalpy change, ∆H in kJ, for the reaction H2O(s) → H2(g) + 1/2O2(g). Use the following information: : +279.9 kJ
Len [333]

Answer:

+ 291.9 kJ

Solution:

The equation given is as;

H₂O ₍s₎ → H₂ ₍g₎ + 1/2 O₂ ₍g₎ ΔH = ?

First, as we know the heat of formation of H₂O ₍l₎ is,

H₂ ₍g₎ + 1/2 O₂ ₍g₎ → H₂O ₍l₎ ΔH = - 285.9 kJ

Now, reversing the equation will reverse the sign of heat as,

H₂O ₍l₎ → H₂ ₍g₎ + 1/2 O₂ ₍g₎ ΔH = + 285.9 kJ

Also, we know that,

H₂O ₍s₎ → H₂O ₍l) ΔH = + 6.0 kJ

Now, adding last two equations,

H₂O ₍l₎ → H₂ ₍g₎ + 1/2 O₂ ₍g₎ ΔH = + 285.9 kJ

H₂O ₍s₎ → H₂O ₍l) ΔH = + 6.0 kJ

-----------------------------------------------------------------------------

H₂O ₍s₎ → H₂ ₍g₎ + 1/2 O₂ ₍g₎ ΔH = + 291.9 kJ
